A pipe coupling hub is welded into an aperture in a valve body by supporting the hub in the aperture and making a circular weld between the hub and the body using a welding machine rotatably mounted on wheels or rollers running around an annular surface of the hub. The hub A, Fig. 4, has four projections 29 with accurately machined surfaces 30 in the same plane, which are supported on members 31, 32 placed on the fabricated valve body 10 to locate the hub relative to an aperture formed e.g. by flame cutting, in the wall 12 of the valve body. The valve body 10 is pivotally supported by mandrels 14 on a frame 18 and is locked in position by a pin 19. The interior of the hub is pre-heated by gas burners to take up the clearance and a small bead is deposited by hand welding to secure the hub A to the body 12. The members 31, 32 are removed, the assembly is inverted and a second hub B, Fig. 9, is located in another aperture in the valve body 10 by means of supporting spacers 41 positioned between the surfaces 30 of the projections 29 and is secured by welding as before. The spacers 30 are removed and a submerged arc welding machine, Fig. 11, similar to that described in Specification 778,373 is mounted on the flange 21 of one of the hubs to deposit an internal weld 62 and an external weld 63 as shown in Fig. 13. The machine may be provided with two heads 53, 54 for making internal and external welds or separate machines may be used. The other hub is welded on in the same manner.

Title: Method of producing etchable metal printing plates or cylinders
IPC: C22F1/00
Filed: 1963-04-10
Abstract: 995,047. Making etching plates; treating castings. B. GROOVE, and K. GROOVE, [trading as GROOVE & WELTER]. April 10, 1963 [April 30, 1962], No. 14401/63. Headings B3A and B3F. A process for the production of etchable metal printing plates or cylinders comprises forming a plate from a casting and mechanically compacting the surface zone thereof. In a first example a centrifugally cast zinc tube, e.g. 600 mm. long by 160 mm. diameter, is turned to size and the outer surface thereof compacted to a depth of 1 to 4 mm. by traversing a spherically ground smoothing roller at a pressure of 25 kg./mm.<SP>2</SP> along its length or by peening or drawing. Alternatively a 2 mm. thick zinc layer is cast about an iron core tube, compacted by peening and ground. The surface of a 5 mm. thick cast plate is similarly peened using 1 mm. diameter balls and an air blast pressure of 7 kg./mm.<SP>2</SP> at a distance of 50 mm. from the plate. The metal used is preferably zinc or alloys thereof, zinc having a 99.99% purity or an alloy thereof containing up to 0.1% aluminium and/or up to 0À05% magnesium. The compacted surface is subsequently etched by the one-stage etching process to produce continuous printing blocks or may be cut into segments for attachment to rotary printing cylinders. The depth of the compacted surface is equal to or less than. the etching depth.

[Class 112] A knot for closing a sack or tying up an article is formed by winding a piece of string or the like loosely on a winding member in at least two relatively staggered and superposed turns, stripping the loose knot off the winding member on to the article, and tightening the knot. The knot is made on a machine comprising a rotary and reciprocating winding tube 1, having stepped lugs 3 and a spring string-gripping arm 7 entering a groove 10 in the tube, and a stripping tube 2, slidable on the tube 1, the movement of the tube 2 being arranged to lift the arm 7. The tube 2 is first advanced to raise the arm 7, the string 9 is passed across the tube 1 through a tension device to a gripper, the tube 2 is then retracted to allow the arm 7 to grip the string, and the tube 1 is then given rotary and reciprocating movements to wind the string on it as shown; the end 32 of the string is drawn through the second turn of the string by a hook 18, both ends are gripped by pincers, the tube 2 is advanced to strip the knot so formed off the tube 1 on to the article, and the knot is then tightened by moving the pincers apart. The string may be used double, as shown, to give a loop 15 for suspending the article. String-cutting means may be provided. The apparatus may be duplicated for tying both ends of a sausageshaped article.

Filed: 1925-06-04
Abstract: 257,353. British Dyestuffs Corporation, Ltd., Perkin, W. H., and Hollins, C. June 4, 1925. Anthraquinonyliminoanthrones; indanthrone.- An anthraquinone derivative containing a primary amino group is condensed, in the presence of calcium chloride or iodine, with a-aminoanthraquinone, alpha-diaminoanthraquinones, or their simple derivatives such as diaminoanthrarufin and diaminochrysazin. The products, which are probably anthraquinonyl-iminoanthrones, are not vatdyestuffs but have affinity for cellulose, acetate on which they yield orange to brown and red shades. According to examples mixtures of a-aminoanthraquinone with 1 : 4-diaminoanthrarufin are heated with calcium chloride or a trace of iodine at 200-250‹ C.; the products are freed from small amounts of indanthrone by dissolving in acetic acid, filtering, and reprecipitating by water. The following are also specified as parent materials :-a-aminoanthraquinone itself, aaminoanthraquinone and 1 :5- or 1 : 8-diaminoanthraquinone, #-aminoanthraquinone and diaminochrysazin.

Abstract: 945,493. Spinning yarns. A. FERD SJOBERG A. B. April 25, 1960, No. 14486/60. Headings D1D, D1F and D1W. Twisted bulked/stretch yarn is made by spinning together a roving of staple fibres e.g. cotton, regenerated cellulose, wool, and a crimped synthetic filament yarn (while the latter is maintained straight by stretching) to form a strand, and intertwisting a plurality of such strands to form a yarn which is then wetted to cause lengthwise contraction. In the spinning frame shown, a wool roving 5 and a crimped yarn 10 of continuous polyamide filaments passes from spools 3 and 4 through drafting rollers 6 and a guide 11, merge at the nip of feed rollers 7 and are spun by apparatus 8 to form a strand (in which the filament yarn constitutes a core surrounded by the wool fibres) which is taken-up on a cap 9. Some strands are spun with S-twist and others with Z-twist and both twisted forms e.g. in equal proportions, are then intertwisted with S- or Z-twist. Wetting e.g. in the course of washing or dyeing, enables the straightened yarn component to revert to the crimped condition under lengthwise contraction of the wool fibre mass so that the fibres assume a crimped configuration and bulk the mass.

Fig. 1 shows the connections from the tracker-bar 10 to one form of selector 12, 19 enabling three different sheets to be used; Fig. 3 shows the construction of the selector with the end portion separated. The part 12 contains three rows of chambers 13 separated from chambers 15 by diaphragms 16 situated over the end of tubes 17 which are connected to the tracker-bar and are bled in the usual way. Corresponding chambers 15 of each row are connected together by tubes and passages 18 connected to the expression-control valvedevices, and the chambers 13 of each row are connected by passages 14 opening into valve chambers 13 of each row are connected by passages 14 opening into valve chambers 21<1> formed' in the part 19 and normally open to atmosphere at 23. Suction is applied at 25. Operation of one of three manually-closed valves so as to open one of the conduits 24 lifts a diaphragm 22 and valve 21 and connects the corresponding passage 14 to suction, so that one passage of a tune-sheet aperture over a tracker-bar orifice the appropriate intensity-control valve is operated owing to the rising of the corresponding diaphragm 16. In another construction, the selector is in the form of a slide valve, operated by a hand-lever or rotary control situated on the spool-box and provided with an indicator. Or the slides (for the treble and bass ends) may be replaced by bellows-pneumatics. The manual' control for the selector may consist of a selective cam-device having a number of surfaces corresponding to the number of positions of the selector.
